Senior🎓
Top SchoolOliver Adria is a freelance web developer and software architect based in Cologne with 11 years of experience building full-stack web applications and APIs using PHP/Symfony, JavaScript (Vue.js, Angular, TypeScript) and AWS-backed databases (Postgres, MySQL). He splits his time between client engagements and running his own niche jobboard, NachhaltigeJobs, which reached 100,000+ monthly pageviews and 18,000 newsletter subscribers—evidence of his product thinking and ability to scale user-facing systems. As a contractor he has delivered API-first architectures, Ionic/Angular frontends and coached teams across startups and enterprises, often taking senior/architect responsibilities. Early work in robotics and C++ plus a background in electrical engineering give him a systems-oriented mindset that informs pragmatic design choices. Colleagues know him for blending hands-on implementation with architectural foresight and for preferring Symfony-driven backend design. He brings entrepreneurial grit, sustainability domain experience, and a track record of shipping measurable growth for his own and clients' projects.
